Declaring a D pointer to a C function

[Johannes Pfau]

From a discussion related to derelict:
How do you write this:
-------------------------------------------------------
alias extern(C) int function(void* test) FTInitFunc;
FTInitFunc FT_Init_FreeType
-------------------------------------------------------
without the alias?
-------------------------------------------------------
extern(C) int function(void* test) FT_Init_FreeType;
-------------------------------------------------------
is not the same!
both are fields containing a C function pointer, but the first field
has D name mangling (_D4test16FT_Init_FreeTypePUPvZi) and the second
has C name mangling: (FT_Init_FreeType, which conflicts with the C
function FT_Init_FreeType)

And a related question from stackoverflow:
(http://stackoverflow.com/questions/6257078/casting-clutteractor-to-clutterstage)
How to write this:
-------------------------------------------------------
alias extern(C) void function(void*, const char*) setTitleFunc;
auto clutter_stage_set_title =
getSym!(setTitleFunc)("clutter_stage_set_title");
-------------------------------------------------------
without the alias?

http://d.puremagic.com/issues/show_bug.cgi?id=2168 and
http://d.puremagic.com/issues/show_bug.cgi?id=4288 seem to be related,
extern(C) seems to work almost nowhere ;-)
